If you want to see a variation of this concept in the wild, in active use by lots of people, check out PICO-8 cartidges. PICO-8 is a virtual game console. I.e. it's an emulator for an oldschool game console that doesn't exist in reality. It's designed to be easy to code for while maintaining the limits and aesthetics of old game computers PICO-8 games are, of course, distributed on cartridges. However because it's a…

This is the coolest thing in ages. The game's code is steganographically embedded in a PNG image containing the screenshot of the game! Wow

Steganography is cooler for sure, but can't PNGs already store arbitrary data in the header? IIRC, the game Spore did that so you can exchange creatures by sending images.

I wish more QR-scanners supported data URLs. I think it would be very cool to distribute tiny web-apps via QR code.

Yeah, let’s make it even easier for people to run random executables that cannot be vetted, preferably on devices tightly coupled to their identities. What could go wrong?

Smartphones are locked down pretty tightly, so I'm not sure how much could actually go wrong compared to what can go wrong with regular apps anway.

Don't worry. There is no malicious code contained within this QR code!

That's what I thought about as soon as I read this. Seems like a great malware installation vector.

Just print out stickers and put them up at restaurants, stores...

I'm still waiting for someone to make an app that encodes and decodes large data into multiple QR codes that are displayed in a moving sequence. That would be the best way to transfer files in physical locations.

Apple has something like this for their new iOS device setup. I don’t think it’s to encode larger amounts of data, but for security they have this circle that constantly changes shape (see around 0:50 in this video for a demo: https://youtu.be/iE03ypWD5xs ). I don’t know for sure how it works, but my first thought was a constantly changing QR-like code.

Someone asked a very similar question on the apple stack exchange[1]. Apple also filed (at least) two patents on the technology[2][3].

For which 99.99999% of users will be using mobile clients to scan the QR code that have no capability of executing the code...

This is very cool, and gives me a thought, what if you did it without "cheating"? That is, what if the whole game including its rules were in the picture? Something like Conway's game of Life but less shape-dependent, maybe utilizing the color to generate behaviors.

You can find the prod executables on https://files.scene.org/browse/parties/2019/assembly19/1k and the placement list and Youtube captures (many prods require quite a hefty GPU to run so YT is the option if you're on a weaker laptop) via http://www.pouet.net/party.php?which=7&when=2019

Thanks!

Yeah I'd much prefer it be a javascript: URL that did all the magic in the browser. Much safer, cross platform, and it would probably work out of the box in existing QR reader apps.
